Cousin.... But yeah...
But no, let me make it weirder. Cause from the spirit trials, it sounds like she also has her past self somewhere inside of her AND something something demon king. So she's basically got four people inside of her. Her current self, her past self, her past as Fiona, and demon king.
This is basically incest, DID version. Which is weirder for me because WHY would anyone make those choices??? Together???
That other girl is her past life and that's her brother.... She seems to be falling in love with her own brother.. It's like incest with extra steps..
